I'm not sure why that say this is a "steel" cat condo? The pieces are made from PVC. It is however, very sturdy. And for the price, I cans't complain. I have 2 cats that want to sleep in the same place in the sun so I thought this would be perfect and it is. They LOVE this bed. The bottom bunk is a super comfy plush cat bed while the top is more of a sling/ hammock type. I was a little wary of the top bunk giving out and my cat falling through but, my 16.5lb cat jumps up in there and sleeps with no problems. Ive had this bed for a few months now and have had no issues so far.
